Characterization of sand boils with grading entropy
Zbornik Matice Srpske za Prirodne Nauke , 2012, DOI: 10.2298/zmspn1222073n
Abstract: Grain size and grain distribution by size are dominant factors determining soil behaviour. The shape and position of a grain distribution curve contain implicit information about the propensity of sand boiling or piping at flood conditions. The author used 1040-grain distribution curves taken from 12 sand boil locations to study the relationship between sand boils, hydraulic soil failures and entropy. The results have justified the hypotheses and indicated some fairly important details for practical consideration. Calculating grain distribution entropy is not “magic” with mathematics: it simply helps put the expected behaviour of soils into a different perspective and promotes orientation for classifying soils according to a new parameter related to grain movement.
Investigation of sand in piping
Zbornik Matice Srpske za Prirodne Nauke , 2012, DOI: 10.2298/zmspn1223115n
Abstract: For the investigation of the grain size distribution of the material washed out from the piping, we used 20 samples originating from different places on the Danube and the Tisza rivers. The grading characteristics of these samples were investigated based on selected grain sizes and the uniformity of gradients. Based on the investigations it has become possible to identify which grain size fractions are likely to be washed out, and how to characterize those fractions. Based on the grain size distribution curves it has been made possible to define the boundaries of the zone susceptible to piping. The zone limits of granular soils liquefied by earthquakes and the zone limits of the soil out washed from piping are very similar. This apparent correspondence already formerly raised the hypothetic question of whether piping occurring during high flood can be simulated by shape to similar surface liquefaction phenomena experienced during earthquakes, as in both cases a volcanic cone is formed through the crater of which water is constantly issuing, dragging away solid particles.
Optimisation by mathematical modeling of physicochemical characteristics of concrete containers in radioactive waste management
Ple?a? Ilija,Na??er? Laslo J.,Davidovi? Milo? D.
Nuclear Technology and Radiation Protection , 2013, DOI: 10.2298/ntrp1301025p
Abstract: A method for obtaining an optimal concrete container composition used for storing radioactive waste from nuclear power plants is developed. It is applied to the radionuclides 60Co, 137Cs, 85Sr, and 54Mn. A set of recipes for concrete composition leading to an optimal solution is given.
Experimental testing of the digital multichannel analyzer for gamma spectrometry measurements
Novkovi? Du?an,Na??er? Laslo,Kandi? Aleksandar,Vukanac Ivana
Nuclear Technology and Radiation Protection , 2008, DOI: 10.2298/ntrp0801043n
Abstract: The results of experimental testing of the digital multichannel analyzer which digitalizes the signal after a preamplifier are presented. The recordings of some of the characteristics of the spectrometer containing a digital MCA, such as full-peak efficiency, net area ratio of the two peaks and the stability of the peak position, were carried out under different input counting rates, with different radioactive sources. The tested MCA has shown some excellent features, like the stability of the peak position over a long-term period and flexibility in the adjusting of optimum measurement conditions. However, the performed tests have also shown some serious and unexpected disadvantages of the digital MCA when it operates under certain circumstances, one of them having to do with the automatic tuning of live-time correction at low-input counting rates.
Low-frequency noise of a Dual-Gate MOSFET in linear region
Videnovi?-Mi?i? Mirjana,Jevti? Milan,NaLaslo
Journal of Automatic Control , 2006, DOI: 10.2298/jac0601037v
Abstract: This paper presents results of low frequency noise measurements for a Dual-Gate MOSFET (DGMOSFET) in linear region. DGMOSFET working conditions are chosen in order to set both inner transistors in linear regime. Results are discussed with the use of the unified 1/f noise model.
New method for determination of temperature in spallation reactions
Jordanov Dragana J.,Grabe? Bojana S.,Suboti? Krunoslav M.,Na??er? Laslo J.
Nuclear Technology and Radiation Protection , 2011, DOI: 10.2298/ntrp1102153j
Abstract: We propose a new method for determination of temperature in spallation events. It is shown that temperature can be determined by applying the friction model of energy dissipation in participant-spectator model of a spallation process. First order estimate of temperature dependence of the participant zone on reaction Q-value is obtained from the Fermi gas model considerations. The heat diffusion process is also discussed.
The direct activity measurement of 133Ba by using HPGe spectrometer
Novkovi? Du?an N.,Na??er? Laslo J.,?ura?evi? Mirjana M.,Vukanac Ivana S.
Nuclear Technology and Radiation Protection , 2011, DOI: 10.2298/ntrp1101064n
Abstract: The direct measurement of 133Ba source activity by the application of the theoretical count rate equations has been recently developed by Novkovi et al. The analytical and Monte Carlo calculation of activity measurement uncertainties were described in previously published papers for the case of one recorded spectra. The procedure of uncertainty calculation for a sequence of successively recorded spectra, enabling the determination of the correlation between peak count rates, is presented in this paper. The uncertainty of activity obtained by the described method is caused by the uncertainty of the experimentally obtained input data and uncertainties of the used nuclear decay data.
A Thunder in the Cloud
Laslo ?ere?,Laslo Horvat,Ivana Horvat
International Scientific Journal of Management Information Systems , 2011,
Abstract: Over the last decade, the endless possibilities which are available on the Internet put the spotlight on cloud computing as a concept and it soon spread rapidly throughoutthe IT society. Many have recognized that this concept is a very fertile ground for thefull recognition of some previously known concepts, such as the concept of softwarereusability, and provides the infrastructure for the development of more securesoftware solutions. It made companies, and their clients, to feel safer than everleading them to one mission - to become a part of the cloud. At the same time, theincreasing number of final users caused enormous quality growth of the variousservices given in the cloud. This kind of evolution, followed by a constant competitionbetween involved contestants, made a stormy surrounding where one leader doesn't have to be a lifetime leader. In this paper we presented the milestones in the evolutionof cloud computing concept with special emphasis on the ongoing developments. Aftepresenting the features of this concept we also took note of the contribution andimpact on the development of cloud computing one of the current leaders in this field.
Chronic candidiasis - pathogenesis, symptoms, diagnosis and treatment
Klajn-Laslo Marija
Zbornik Matice Srpske za Prirodne Nauke , 2009, DOI: 10.2298/zmspn0916267k
Abstract: The yeast named Candida normally colonizes the gut and vagina without causing any sign of its presence. It is a commensal and opportune fungus but in certain conditions it turns to be pathogenic, causing chronic disturbances in any part of the body. The pathogenesis is complex, signs and symptoms are non-specific. The colonisation is difficult to distinguish from invasive disease. The current diagnostic methods do not always allow a definitive diagnosis to be made. Treatment is complex, individual and no protocol can be created. The author tries to give an overview of the Candida related problem.

Animal Biology & Animal Husbandry , 2010,
Abstract: Since the Romanian literature is pretty low quality data on the influence of hygienic quality ofraw materials and preparations of meat, in our research we intend to pursue these issues in pork andbeef quality I and II. Bacterial load of raw meat products brought in meat technology varies dependingon its quality. Thus, the total number is 44,640 germs / g beef I and 86,640 / g beef II. The number ofcoliform bacteria is 329 / g beef I and 420 / g beef II. Protein derivatives stands at a higher bacterialload in soybean meal (5.04 million / g) than in texturate protein (4,000 / g). Number of sporulatedaerobic germs in soy flour is 4.115 million / g and in the protein texture 1,000 / g. In soy flour therecorded number of coagulase-positive staphylococci is 1,250 / g and the number of sulphite-reducingclostridium is 250 / g, compared to the number of coagulase-positive staphylococci observed in proteictexturate, 420 / g, and sulphite-reducing clostridium which is absent, but it is found in texture to soymeal micelium a greater number (161,000 / g). High value bacterial load in the emulsion impose proteinderivatives obtained from them to cool as soon as possible after production to prevent multiplication ofmicroorganisms.
